On Pluto, you would weigh 6.32% of your weight on Earth. Multiply your Earth weight by 0.0632: a 70 kg person would read 4.42 kg, and a 154 lb person 9.75 lb. That is 94% lighter than on Earth. Your mass does not change; only the pull on it does.
The surface gravity is 0.62 m/s² against 9.81 m/s² on Earth. Weight is mass times local gravity, W = m × g, so the scale reading is your Earth reading times 0.0632.
Weight on Pluto by Earth weight
Each row is a person’s Earth weight and what the same person reads on Pluto. The pounds column converts the kilograms (1 kg = 2.20462 lb); the ratio 0.0632 is the same for any unit.
| On Earth | On Pluto (kg) | On Pluto (lb) |
|---|---|---|
| 40 kg (88.2 lb) | 2.53 kg | 5.57 lb |
| 50 kg (110 lb) | 3.16 kg | 6.97 lb |
| 60 kg (132 lb) | 3.79 kg | 8.36 lb |
| 70 kg (154 lb) | 4.42 kg | 9.75 lb |
| 80 kg (176 lb) | 5.06 kg | 11.1 lb |
| 90 kg (198 lb) | 5.69 kg | 12.5 lb |
| 100 kg (220 lb) | 6.32 kg | 13.9 lb |
Calculated as weight × 0.62 ÷ 9.81. A bathroom scale calibrated on Earth would show these values.
Why gravity is 0.62 m/s² on Pluto
Surface gravity follows from the body’s mass M and its radius R: g = G M ÷ R². The simulation uses a radius of 1,188 km, which with g = 0.62 m/s² corresponds to a mass of 0.0022 Earth masses.
Pluto’s gravity is 6.32% of Earth’s, about one sixteenth. A jump that rises 50 cm on Earth would carry you 7.91 m up, and you would hang in the air for about 10 s, long enough to count to 10.
Pluto is a dwarf planet about 2,380 km across. The only spacecraft to visit was New Horizons, which flew past in 2015 and did not land, so every number here comes from tracking its path, not from standing on the surface.
A jump and a fall on Pluto
Gravity sets more than weight. The take-off speed that lifts you 50 cm on Earth would raise you 7.91 m on Pluto, in a jump lasting 10.1 s against 0.639 s on Earth. A ball dropped from 2 m takes 2.54 s to land, compared with 0.639 s on Earth.
Escape speed, the speed at which you leave for good, is 1.21 km/s, against 11.2 km/s for Earth. It does not depend on your mass.

Frequently asked questions
How much does a 70 kg person weigh on Pluto?
4.42 kg (9.75 lb). The ratio to Earth is 0.0632, from g = 0.62 m/s² against 9.81 m/s².
Does my mass change on Pluto?
No. Mass is the amount of matter in you and stays the same everywhere. Weight is the force gravity puts on that mass, so it is the weight that changes, to 6.32% of its Earth value.
How do I work out my weight on Pluto?
Multiply your Earth weight by 0.0632. In kilograms or pounds the answer comes out in the same unit, because the ratio has no unit.
How high could I jump on Pluto?
A jump that rises 50 cm on Earth would rise 7.91 m on Pluto, because height scales as 1 ÷ g for the same take-off speed.
